' To all whom-it may concern:

, Be it known that we, JOHN'S. Forums and vIRoY H. Po's'roN, citizens of the United States, residing at Flat River, in the county of St; Francoisand State of Missouri, have invented certain new and useful Improvements in Permutation-Padlocks, of which permutation disks connected in such a mannor asto permit of rotation of the permutation disks to operate the bolt.

A further object of the invention is to provide" an intermediate disk in which a passage is formed for the guiding leg of the shackle and a recess for the bolt and the locking leg of the shackle, the bolt being held in place in the intermediate or bolt disk by the laterally abutting permutation disks and also moved by rotation of the permutation disks into and held thereby in a shot or locking position.

It is a further object of the invention to provide a spring for the bolt so that it will be shot into an unlocking position when the permutation or combination members have been rotated or moved into a position to unlock the device.

Further objects of the invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawing :-Figure 1 is a vlew in side elevation illustrative of one form of our invention. Fig. 2 is an edge view thereof. Fig. 3 is a sectional view on line 33 of Fig. 2, showing the parts in a locked position. Fig. 4 is a view similar to Fig. 3

showing the parts in an unlocked position. Fig. 5 is an inside view of one of the permu tation or combination members. 'Fig. 6 is a perspective view of the improved bolt.

Like characters of reference designate similar parts throughout the different figures of the drawings.

As illustrated, 1' designates the shackle having a relatively long guiding leg 2 and a relatively short locking leg- 3. The locking leg 3 is reduced, as indicated at 4 and is provided with a locking notch 5, as clearly shown in Fig. 4. The guiding leg 2 is reduced, as indicated at 6 and its terminal end Specification of Letters ratent.

. is upset or enlarged, as shown at 7 for a purpose which will presently appear.

The body of the padlock includes an in termediate or. boltmember 8 which is shown as a disk of circular form and which is provided with a guiding passage 9 for the reduced portion 6 of leg2 of the shackle.- The guiding passage 9 "terminates in an opening 10 in which the enlarged retaining end 7 slides. .The opening 10 is dimensioned as regards its length,so that when the shackle is in the position shown in Fig. 4, the retaining end 7 will act as a stop to prevent the shackle from being wholly withdrawn, and when the shackle is in the position shown in Fig. 3, the opening 10 is of suflicient length to permit the locking leg to be inserted fully into a locking position.

On each side of the intermediate or bolt withrespect to each other and, which are of the same diameter with respect to the intermediate bolt disk 8 so that their peripheries will be'flush, the permutation or combination disks 11 serving to close the opening 10. Each permutation disk 11 is provided with a bolt-retaining groove 12 which is shown disposed concentrically with respect to the center of the disk in which it is formed so as to constitute an annular groove. Each groove 12 is provided with a notch 13 having an actuating portion 14, the purpose of which will presently appear. We connect the permutation disks 11 withthe bolt disk 8, centrally of the same, and by means of a simple form of rivet, as indicated at 15. In order to prevent disassembling of disks, the ends of the rivet 15 are upset, as indicated at 16, and the upset portions will be made so that the permutation disks may be relatively freely rotated with respect to the bolt disk 8.

We'will next refer to the form of bolt employed and the manner in which the same is operated in connection with the permutation or combination disks 11. The bolt disk 8 is cut away, as indicated at 17, to form a bolt cavity bolt 18 is shapedto be reciprocated in the cavity 17 from the position shown in Fig. 3 to the position shown in Fig. 4:, and vice versa. The bolt is ual in thickness to the thiclmess of the bolt disk 8 and is held in place in the cavity by the permutation disks 11. Said bolt 18 is provided with oppositely for receiving a bolt 18. 'The projecting studs 19 which extend into the groove 12' of the permutation disks 11, as

indicated in Fig. 3. The bolt 18 is also pro- 'vided with a locking nose 20 adapted toengage the notch 5. A notch 21, in the bolt' 1 8, receives the upper end of a sprin 22 which is'fitted in a recessed portion 23 in the bolt disk 8. The spring 22 is tensioned .to normally retract the bolt so as to hold the same in an unlocked position and the spr ng is held in place in the cavity. 23 by the permutation disksll. 7 Assuming that the'parts are in the pos tion shown in Fig. 4, the shackle 1 w ll be shifted into the position shown in Fig. 3 and one or both, but preferably both of the permutation disks 11 will be rotated 11 13. .contraclockwise direction, from the position shown in Fig. 4,.so that theactuating portion 14 will engage the studs 19 to cause the bolt to be shot from the position shown in Fi 4 to the position shown in Fig. 3. It wil be seen that the studs 19 move in a straight line and that they will ride upwardly on the actuating portion 14 as the disk 11 or both disks are rotated in a contraclockwise direction until the studs 19 reach the grooves 12, as shown in Fig. 3, in which position the bolt will be locked or retained against movement from on agement with the locking leg of the shack e. In unlock-'- ing the padlock, it will be necessary to rotate both of the combination disks 11 until the notches 13 register with the studs 19 to permit retraction of the bolt by the spring 22. This position is shown in Fig. 4 and it will be readily seen that when the shackle is unlocked it can be partially withdrawn, the retaining end 7 preventing the shackle from being wholly detached from the body of the loc It is believed that the advantages and utility of our invention will be clearly under stood from the foregoing descriptioii' grand while we have herein shown and described one specific form of our invention, we do not wish'to be limited thereto except for such limitations as the claims mayim port.
